I have a grand caravan, with a 3.8l engine.

The s-belt slipped off on my way to work, and I went to put pressure on the tensioner, and the bolt snapped in half.

I drove the van up on ramps, and was able to access the 15mm nut on the back of the tensioner. I went to O'Riley auto parts and they showed me the replacment, and then it was a snap. I used a 3/8" ratchet with the 15mm socket and two 3" extensions. It came right off, and the other one went on easily. I had a 2x2 piece of wood that I used to help hold the tensioner in place, while I worked from the back side.

How do you change the serpentine belt on a Dodge Caravan?

What you need is a ratchet 15mm socket. Losen the idler then slide off the serpentine belt off. There should be a diagram for routing the belt if not draw a diagram before removing it. Replace the serpentine belt crank it 2 or 3 times but don't start the engine. The 4th time start the engine this time the as the engine is idling eyeball the belt agaisnt the tensioner idler and crank pulley make sure the serpentine is algined. A Note: Make sure that you have identified the tensioner pulley as apposed to the idler pulley. With the 15mm socket on the tensioner pulley's bolt, rotate it clockwise and this will release the tension on the belt, or in the case of installing a new serpentine belt, allow you to get it where it belongs. This is the case on my 1997 Dodge Caravan, and probably other year makes. Best of luck- Bryan 1993 Dodge Grand Caravan: Rotating the tensioner pulley's bolt clockwise was the way to replace my belt. By the way, the tensioner pulley in my van was one of the smaller ones in the middle of the whole system, attached to a silver arm coming off the tensioner. Good luck...
